Why would we need such? And how is the term "local" defined here?
Local to what?

Please explain why? We do have timer support on armv7, right?

Why are you adding something new, then? If you are tring to replace
existing code with some better implementation, I would expect to see
code being removed, too?

Please understand that completeness has never been any goal for
U-Boot, on contrary.
